Context menus on tappy links in iOS open context menu but also already follow link

[patrickhlauke]

When using tappy on links, long-pressing a link in Safari/iOS opens the context menu - as soon as the finger is lifted off the screen, the link is followed, despite the context menu still being open.

Arguably, this smells like a bug in iOS - testing the event flow using http://patrickhlauke.github.io/touch/tests/event-listener_link.html it seems that when context menu is shown, Safari/iOS doesn't consistently fire touchcancel; in fact, if you keep the finger pressed, you can actually still scroll the page underneath the context menu and it fires touchmove events, and sometimes it then fires touchend if you lift the finger while the context menu is shown. Not sure if this is something that can be caught/prevented by tappy though...

filed an iOS bug here FWIW https://bugs.webkit.org/show_bug.cgi?id=153064

As I don't think there's realistically anything that can be done at tappy's end to consistently work around this iOS bug, I'm closing this (in the hope that Apple fix this at source instead)
